Specification of Letters Patent.

Application riled March 23, 1820. Serial No. 388,102.

To all whom it may concern:

Be it known that 1, JOHN ERIKAINEN, a citizen of the United States, residing at Pelkie, in the county of Baraga and State of Michigan, have invented new and useful Improvements in Pumps, of which the following a specification.

This invention comprehends the provision of a combined turbine and pump, the former being utilized to operate the latter, and from the driven shaft of which other machinery may be suitably operated.

In carrying out the invention, 1 associate with the piston rod of the pump a double rack bar which operates between and meshes with a pair of pinions,'means of novel construction being employed to alternately ro tate the pinion in opposite directions to impart reciprocatory motion to the piston rod.

To this end, I preferably employ a master gear disposed in alinernent with a pair of small gears fixed upon the shaft carrying the above mentioned pinions, the teeth of the master gear being interrupted to alternately mesh with the teeth of the respective gears for driving the pinion alternately in opposite directions for the purpose above mentioned.

Another object of importance resides in the provision of a plurality of pivoted blades normally disposed within pockets formed in the periphery of the rotor of the turbine,

with means for positively moving each blade at a predetermined interval from its pocket to an active position.

A still further object of the invention resides in the provision of means for limiting the initial outward movement of each blade under the influence of the positive actuating means therefor, each blade wien released gravitating to a full active position.

The nature and advantages of the invention will be better understood when the following detail description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application like numerals of referenceindicate similar parts in the several views and wherein Figure 1 is a side elevation of'the combined turbine and pump.

Fig. 2 is an end elevation.

Fig' 3 is a vertical sectional view taken through Fig. 1.

Fig. i is a view in elevation of one of the blades of the rotor.

Fig. 5 is a view in elevation of the supply tank.

Referring to the drawings in detail, 10 indicates generally the foundation upon which the pump A and turbine B are suitably mounted. The cylinder 11 is provided with valve controlled inlets 1 and valve controlled outlets 15, a supply pipe 16 communicating with the inlet as shown. The outlet pipe 17 may be directed to any particular location, to convey the water to its proper destination. Carried by the piston rod 13 is a cross arm 18 to each end of which is secured in any suitable manner, a double Patented May 10 1921a rack bar 19 for a purpose to be presently to'n 12.

To this end, I make use of a master gear 25 disposed in alinement with the gears 22 fixed upon the respective shafts 20. The teeth 26 of the master gear are interrupted to provide toothless portions 27. The teeth of the master gear are arranged to mesh with the gears 22 in a manner to alternately rotate said gears in opposite directions, this direction of rotation being imparted to the pinions 21 fixed upon the same shaft that carries the gear 22, so that reciprocatory motion is imparted to the piston 12/ The master gear 25 may be rotated in any suitable manner, but in this specific instance is operated by means of the turbine to be hereinafter described. As the master gear rotates, onesection of the teeth 26 is initially brought into contact with one ofthe gears 22 rotatingthe latter in the direction indicated by the arrow, and thus actuating the rack bars 19-to1110ve the piston 12 onits downstroke within the cylinder. WVhile the teeth of the master gear are rotating one of the gears 22 in the manner just stated, the non-toothed portion 27 passing over the companion gear 22, a fact which spaces the master gear 25 from the latter mentioned gear 22 so that this gear is allowed to rotate toward the gear 22 which is being actuated under the influence of the master gear 25. In other words byreasons of the interruptions of the teeth 26 on the master gear, only one jof'the gears 22 meshes with the teeth of the master gear at one time. When the teeth of the master gear moves out of engagement with the'iirst of the gears 22 in order, the piston 12 has completed its down stroke, the said teeth now moving into engagement'with the next. gear 22 so as to reverse the direction of rotation of the lat ter, whereupon the said bars 19 are actuated to move the piston 12 upwardly in the cylinder 11.. This construction and arrange ment of partsprovides for a positive and eflicient operation of the pump.

The master gears 25 are loosely mounted uponthe shaft 52, and when use is desired to operate the pump, a sliding clutch 52 keyed upon the shaft 52 is moved into engagement with the hub of the adjacent master gear. Manifestly, when the clutch members 52- ''are separated from the hubs of the master gears, other machinery may be operated from the shaft 52 without operating the pump.

The turbine indicated generally at B is arranged for rotating the rotor 31. The casing 30 communicates with the reduced extremity 32 of a water supply tank 33 which may be of any suitable capacity and cross sectional configuration.

A slide valve 34 operates to control the communication between the supply tank 33 and the casing 30, the valve 34 moving between guides 35 and controlled in its movement by an adjusting screw 36. The casing 30 beneath the rotor 31 is extended to provide a discharge pipe 37, the other end of which is equipped with a valve 38 of any suitable construction. The water flows from the tank 33 into the casing 30, operatingthe rotor 31 in a manner to be presently described, and then passes through the discharge pipe 27 and the valve 38.

The rotor 31' is provided with a plurality of pockets 39 in the periphery thereof and at suitably spaced points, each of these pockets being designed to accommodate what is herein termed a blade 40. These blades normally lie within the pockets 39 flush with the periphery of the rotor, but are loosely mounted on shafts 41, one shaft being provided with each blade and journaled in bearings'formed in the pocket 39. By reason of this construction, each blade 40 is permitted to move from its pocket 39 to an active position at a predetermined interval during the rotation of the rotor 31. Each blade is provided with a central opening 43, which when the blade assumes its full active position is covered or closed by a pivoted valve 44 arranged at one side of the blade and gravitating to its active position.

For the purpose of positively moving each blade 40 from its pocket 39 at the proper time during the rotation of the rotor 31, I employ a toothed segment 46 fixed upon the shaft 41 and projecting inwardly from the periphery of the rotor 31. Obviously there is one of these toothed segments for each of the shafts .41, or in other words for each of the blades 40. Fixed to the casing 30 is a curved rack bar 47 with which the teeth of each segment 46 meshes, in successive order during the rotation of the rotor 31. segment 46 is provided with a relatively long tooth 48 which initially meshes with the rack bar 47 and as the rotor operates the teeth of the segment 46 meshing. with the rack bar 47, operate to rotate the shaft 41 with which it is connected. Fixed upon this shaft is a collar 49 provided with a lug 50 which operates in a notch 51 provided in the hub or bearingof the blade 40. As will be understood, there is one of these collars for each blade. Consequentlywhen the shaft 41 is partly rotated through the instrumentality of the segment 46, the lug 5O bearingagainst one wall of the notch 51 moves the associated blade 40 from its pocket 39 to an active position, and in other words to an angle ap- Each proximately of 45 as shown in Fig. 3. As i the rotor continues .to rotate, the segment moves over the rack bar 47, during which time, the lug 50 is in contact with the opposite end of the notch 51, thereby holding the blade 40 in the position illustrated in Fig. 3. \Vhen the segment 46 is moved fully out of engagement with the rack bar 47 the blade 40 gravitates to its'full active position as shown. As the rotor 31 continues to rotate,

each of the fully opened blades is brought I into contact with the casing 30 and thereby moved to its closed position within this pocket 39.

In practice, the tank 33 is supplied with water from a suitable source, subsequent to which the valve 34 is opened as is also the valve 38. The water is thus admitted to the casing 30 to operate the rotor '31; As the latter rotates, the segments 46 are successively brought into active association with the rack 47 to positively move each blade from within its pocket 39 at a predetermined interval. During the continued rotation of the rotor, and the separation of the segment 46 from the rack47 each blade gravitates to its full active position, in which position the valve 44 closes the opening 43 so that the full force of the water'passing through the casing 30 is utilized to time the rotor 31. Th master gear 25 is preferably fixed'upon the driven shaft 52 to which the rotor is While it is believed that from the foregoing description the nature and advantages of the invention will be readily apparent, I desire to have it understood, that what is herein shown and described is merely illustrative oi one embodiment of the invention to which I do not limit myself, and that such changes may be resorted to when desired, as fall within the scope of what is claimed.

Having thus described my invention what I claim as new is 1. In a turbine, a casing a rotor journaled within the casing, a water supply tank communicating with the casing, said casing having a valve controlled outlet, a valve controlling the communication between the tank and said casing, said rotor having a plurality of spaced pockets, a blade normally positioned in each pocket and pivoted for outward swinging movement, each blade having an opening, a valve pivotally associated with each blade and adapted to gravitate to a position to close said opening, and means for positively actuating each'blade at a predetermined interval to move the blade from its pocket.

2. In a turbine, a casing, a water supply tank communicating with the casing, a valve controlling said communication, a rotor journaled in said casing, said rotor having spaced pockets, a plate normally positioned in each pocket for outward swinging movement, a stationary rack bar, a tooth segment fixed upon the pivot of each plate and meshing with said rack bar for the purpose specified, a collar fixed upon the said pivot, a lug carried by the collar, and the bearing of said plate having a notch in which said lug operates for the purpose specified.

In testimony whereof I ailix my signature.

JOHN ERIKAINEN.
